SIGNAL-Winn HANGER.

Appncatinmea November 7, 1923. serial* No. 673,331.

l ZThis invention relates to an improved sigf nal wire hanger, being particularly designed ior use'in connection with my improved signaling system lfor mines as disclosed in Pat-kk ent No. 1,523,805, dated January 2Q, 19725,

and seelrs t'o vprovide a hanger whieh'may bereadily attached to the usual trolley wire hanger Oi a 'inine'torsupporting a conductor .Y

wire Oyer'the trolley wire so that ,when the trolley vwire'is pressedv upwardly by the trolley ofla mine car, incident to the Vtravel of the caralong the mine tracks, a circuit` will vbe closed through lthe conductor wire for eiieigizingcert'ain signals.v i

In the drawings: j j y Figure 1 is` a side elevation showinginy iinprovedhangerin connection with a conventional trolley wire hanger,

Figure 2 is a plan View of the assembled hanger,r and j Y Figure 3 is a detail sectional viewon 'the line 3-4-3 of Figure 1, showing the *manner in which thecOnductOr wirehanger is secured in place. y

Referring nowniore particularly to the "drawings, I have shownmy improved conductorwire ,hangery in connection with a Ycon- `ventional hanger. for ythe trolley 'wire ot a mine. 'llii's'trolleywire hanger includes the lusual insulator from the lower end of which extends a stud 11 and threaded over said stud is a stem 12 upon which are pivl oted coactiiig elongated jaws 13 to. engage a trolley wire, as conventionally illustrated at 14. Surrounding the stem 12 to coact with the jaws 13 is a wedge member 15' and threaded upon the enlarged upper end of the stem is a nut 16 adjustable liorvbindingV the jaws in engagement with the trolley wire.

Coming now more particularly to the subject of the present invention, I employ a pair oi' companion clamping jaws 17 and 18 respectively, bent at their lowei margins to define semi-cylindrical gripping portions 19 mating to define a sleeve and extending through the upper margins of the jaws'near the ends thereof are clamping bolts 20. As brought out in Figure 2, the jaws are curved longitudinally to extend at one side of the trolley wire hanger while the jaws are of such length that the ends thereof terminate near the plane of the trolley wire, andV tit ting between the portions 19 of the jaws is f a longitudinally curved tubular insulator 21I vaccominodating a conductor wire 22 therethrough. Thus, as will be seen, the boltslmaybek adjusted for 'binding'the jaws in4 engagement with the insulator while the portions 19"ojt` y'the jaws will provide a protecting sheath for the insulator.v Rising Yfrom the jaw "18 niedially thereof is an angle-shaped'arni or'bracket 23 the laterally directed tree end 'portionoi which is `pro' yided with a-slot 24 to accommodate the stud 11 `of they insulator 10. Accordingly, the tree endo't the'arin may, as showinin Figure 3, be slippedl over said stud between the upper end ot the stem 12 and the insulator when the stern may be adjusted uppwardly upon the stud `for kfirmly clamping the arm. However, the Yl'ree ends of the ears defined byfthey slot2/1 are, as rbest brought out in Figures 1` and 2, bent'laterally downward so that said ears will coact -withtlieupper end ofthe sleeve tor 4locking they arm .against displacement. Thus, the hangerwill be rigidly and securely'mounted jupon tlietrolley vwire hanger "for 'supporting the'conductor wire 23 above thetrolley wire iii ,close proximity thereto.

I lavi'ng thus 'describedthe invention, what is clainidlas newis l. The combination `with a. trolleyr wire hanger, and a trolley wire supported by said hanger, of an auxiliary hanger mounted upon the trolley wire hangerto extend at one side thereof, and a. conductor wire supported by said auxiliary hanger above and to one side ot the trolley wire in close proxl imity thereto whereby a trolley wheel may move the trolley wire upwardly and have. contacting engagement with both wires.

2. A wire hanger including companion longitudinally curved clamping jaws to accomnio'date a wire therebetween, and means for adjusting the jaws with respect to each other, one of the jaws being provided with a supporting arm slotted atits free end to accommodate a supporting stud.'

3. A wire hanger including companion longitudinally curved clamping jaws bent at their lower margins to define gripping por' tions to extend about an insulator for a wire, and means extending through the upper margins of the jaws for clamping the gripping portions thereof in engagement with said insulator, one of the jaws being provided with a supporting arm. I

l. A signal wire hanger including comf panier; longitudinally curved jaws mating to receive n wire therebetween, and means `for adjusting the Jaws with respect to each other`I one of the iaws being provided with. an Yup` combination with a pair ol ccntractible.earsl for securing an electrical conductor7 suspending means and clamping means for the ears,V of means carried byy the suspending means for clamping and supporting a second electrical `crnidnctor .independently of the first-mentioned electrical conductor above and te one side oit the lust-mentioned conductor in close proximity thereto whereby a trolley wheel may move the lirst-inentioned conductor upwardly and have contacting engagement with both conductors.

(i. ln a device of the class described, the combination with a pair of contractible ears tor securing en electrical conductor. suspending means and clamping means for the ears, oit `means carried by the suspending means for tiXe'dly clamping and supporting u second electrical conductor indepemlently or' the inst-mentioned electrical conductor `above and to one side of the iirst-ineinioned conductor in close proximity thereto whereby a. trolley wheel may more the first-inentioncd conductor upwardly and have contacting engagement with both conductors.

7. A suspending device for a trolley wire and e. second cooperating wire comprising means for iXedly clamping the trolley wire, and an auxiliary means carried by the i'irst means for fixedly clamping the second wire independently of the trolley wire above and retenez to one sident the trolley wire in close proxin'iity thereto whereby a trolley wheel may more the trolley wire upwardly and have contacting engagement with both wires.

8. suspending device tor a. Vtrolley wire and la second wire comprising means tor lixedll clamping the trolley wire, and auxiliary means carried by the said first means tor tixedly supporting the second wire independently of the trolley wire near the plane tl'iereo'l and in parallelism with the trolley wire and spaced above and to one side of the trolley wire in close proximity thereto whereby a trolley wheel may move the trolley wire upwardly and have ci'intacting engagement with both wires.

f). The combination with a main hunger, an insulator' supporting said hanger, and a fire carried by the hanger, oit an auxiliary hanger having coactingjaws. one et' which is provided with an arm clamped between the main hanger and said insulator' 'tor supporting the auxiliary henger` and a second wire supported between the aws of the auxiliary Ao' above end to one side of the lirst mentioned wire whereby a trolley wheel ein gaging the lirst wire mayrnoye the saine upwardly and hare contactingengageinent with both wires.

it). The combination with main hanger,

and a` wire supported by the hanger, of anv auxiliary hanger carried by the main hanger and provided with longitudinally curved jaws extending at one side ot' the main hanger in spaced relation thereto7 and a second wire supported by said jawsclose to said first mentioned wire.

In testimony whereof I allX my signature.
